Carnacki, the Ghost-Finder

UK first and true first: Eveleigh Nash, London, 1913, six stories — census claim confirmed. The 1947 edition (Mycroft & Moran, the Arkham House imprint, Sauk City, Wisconsin; 3,050 copies; edited by August Derleth; dust jacket by Frank Utpatel; c. 241 pp.) is the first US edition and the first ENLARGED edition, adding three stories — 'The Haunted Jarvee' (published posthumously in The Premier Magazine, 1929), 'The Hog' (Weird Tales, 1947) and 'The Find' (previously unpublished) — for nine in total. Both are legitimately collected, and the census is right that both states matter, but the 1947 is a textbook 'first thus' trap: it is the first book appearance of those three stories and the first US printing, NOT the first edition of the collection. Catalogue it precisely as 'first American / first enlarged edition,' never as 'first edition.'
